A billiard ball traveling at 3.4 m/s has an elastic head-on collision with a billiard ball of equal mass that is initially at re

Tpy6a [65]

Answer:

Explanation:

Given

Initial velocity of first billiard ball $u_1=3.4\ m/s$

Initial velocity of second billiard ball $u_2=0\ m/s$

After collision first ball comes to rest

suppose m is the mass of both the balls

Conserving momentum to get the speed of second ball after collision

Initial momentum $P_i=mu_1+mu_2=m\cdot 3.4+0$

Final momentum $P_f=mv_1+mv_2$

where $v_1$ and $v_2$ are the speed of first and second ball respectively

$P_i=P_f$

$m\cdot 3.4+0=0+m\cdot v_2$

$v_2=3.4\ m/s$

thus speed of second ball after collision is equal to speed of first ball before collision

Can someone help me :)

Mamont248 [21]

Answer:

mass= 60kg

velocity= 10m/s

momentum = mass × velocity

p=m×v

p= 60×10

p= 600kgm/s

How did the invention of movable type change society?

alexdok [17]

The moveable type drastically changed society. Its primary impact was the distribution of knowledge. Since people could now type books, rather than handwriting then, literary works could be shared faster than ever before. This had a massive impact on education.
